How can I undo the damage from a DIY furniture refinishing project?

I tried to hide minor scratches on my dinning room formal table, with a do it yourself project. i lightly sanded the table top to repaint it the same color. I was told to use rust-oleum high performance protective enamel, oil based. Afterwards I let it dry for 48 hours. Now I have a hot mess. The table has splotches of uneven color, everything you sat on it leaves it traces and the finish is dull. I have pictures as a reminder and a "told you so," husband. Professional help is not an option.
